LINER FOB LOCOMOTIVE DRIVING-BOXES AND THE LIKE.

Specification of Letters Patent.

Patented Jan. 11, 1910.

Application filed September 3, 1969. Serial No. 516,085.

To all whom it may concern: Be it known that I, GRANT HALL, a subect of the King of Great Britain, residing at the city of \Vinnipeg, in the Province of Manitoba, 1n the Dominion of Canada, have .shaped grooves in the box.

The objects of the invention are'to devise a liner for locomotive driving-boxes or the like, which will be of simple and cheap construction and readily set in position without the necessity of screw or other bolt fastenings, and at. the same time be readily replaced or renewed as required.

In the drawings, Figure l is a side elevation of one end of a side frame of a locomotive, showing the driving-boxv and liner thereof in section. Fig. 2 is a sectional perspective view of the driving-box and liner. Fig. 3 is a perspective detail view of the liner. Fig. 4c is a plan view from. the under side of the driving-box, showing the liners fitted thereto, and having squared side flanges. Fig. 5 is a plan view from the under side of the driving-box, showing the liners fitted thereto, and having dovetailed side flanges.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is one end of the side frame of a locomotive or the like, comprising the top ,bar 2, and the frame legs 3 between which the driving-box is situated.

4 is the driving-box, which may be of any standard type, and here shown as customarily formed with the body portion in inverted U-shape for the reception of the journal. brasses 5, in which the axle 6 of the drivingwheels runs.

7 are the side flanges of the driving-box fitting on either side of the frame legs 3, whereby the driving-box has avertical movement betwfiensaid -frame legs governed in the customary manner by the saddle 8 sur- ,mounted by the spring 9, said spring being connected to the side frames by the suspension bars 10.

"The arrangement of the saddle springs and suspension bars may be altered to suit any desired conditions, and do not form any part of my invention, said parts being referred to in order to make the present specification comprehensive in describing the movement of the driving-boxes between the frame legs. I

11 are the driving-box liners extending across each side of the driving-box between the side flanges 7, thereof. I have the side flanges l2 tapered from the lower end thereof toward the top and fitting into correspondingly -tapered grooves 13 made in the side flanges 7 whereby the liners 11 may be wedged between the side flanges 7, and the side flanges 1:2 thereof fit snugly into the correspondingly-shaped grooves in the side flanges 7 of the box, and firmly se-,

cure the liners in place having a similar effect as the driving of a tapered key. After the liners have been placed in position in the boxes, the metal at the lower end of the box may be peened over, the lower edge of the liner and firmly hold the same in position, so that no bolt or screw fastening is neces sary. After extensive wear if the liner should tend to drop, it cannot be lost from the driving-box, as it will contact with the cross-bar 1 T suitably bolted between the legs 3 at the lower end thereof, as customary in the construction of driving-box frames. If desired, however, small studholes 15 may be used to retain the liner in position, said bolts being inserted in correspondingly-threaded orifices in the lower end of the sides of the box, so that the head of the screw partly covers the lower end of the liner, as illustrated in Figs. 4 and 5. It may also be mentioned that if desired the side flanges of the liner may.be dove-tailed, as shown in' Fig. 5, and the grooves in the box'correspondingly cut, whereby the liner will be more securely held in position and be less liable to work loose.

\Vhat I claim as my invention is:

1. In a device of the class described, the combination with a'driving-box for locomotives or the like having side flanges and grooves on the inner face of said side flanges at the base thereof and tapered from the lower end of said driving-box and a threaded The liners 11 orifice at the lower end of the side of said driv'ingbox, of a liner extending between said side flanges and having side flanges fitting said grooves and correspondingly tapered and a cap-screw inserted 1n.said

dove-tailed grooves 011 the inner face of said side flanges at the base thereof and tapered I from the lower end of said driving-box and a threaded orifice at the lower end of the eeaose side of said driving-hon of a liner extending between said side flanges and having dovetailed side flanges fitting said dovetailed grooves and correspondingly-tapered and a cap-screw inserted in said threaded orifice and having the head thereof extending over the lower end of said liner.

Signed at the city of Winnipeg, in the Province of Manitoba in the Dominion of Canada, this ltth day of August 1909.

GRANT HALL. In the presence 01 W. MADELEY CRICHTON, J. ROBERTS.
